RE: How To Create A Live Session Counter
Just typed in the code from this article and it works AWESOME.

RE: How To Create A Live Session Counter
you could use an application level array/structure. you wouldn't have a "true" live counter, because people that don't "log out" would only be tracked by timeouts. close enough for gov't work, though. :) Chris Olive, DOEHRS Website Administrator -Original Message- From: AustralianAccommodation.com Pty.

RE: How To Create A Live Session Counter
We built something like this as part of an anti-data-mining script. Basically, we kept a structure in the Application scope that was a pool of Session IDs (keys) and last time visited (values). When each page was hit this time was updated and there was a chance that a "garbage collection" routine would be run. This routine just looked through the structure to see which sessions had timed out and removed their associated keys. Since this was done often (about once a minute) it added minimal overhead and generally wasn't even noticeable. (The garbage collection took less than 10ms in most cases.) We eventually even extended it to track the last 10-15 URLs on our site that the user had hit, which we then used to figure out how we could better organize our site. We also added a real-time viewing interface to it so that you could see what sessions were active, what pages they'd hit, and how quickly they were traipsing through the site. This made the bean-counters *extrememly* giddy, as they now had visible real-time proof that the site was doing what it was supposed to. The anti-data-mining portion was simple, too. Since we knew the last couple of hits that the user had done, if they were searching our database too fast then we knew they weren't human and "froze" the session for a minute. During that time they wouldn't see anything but a nice "please slow down" page. We've only trapped 2 or 3 actual humans since we started it. We have trapped a few offline browsers/caching clients, but that's okay with us, as our data is meant to be real-time anyway. The whole thing wasn't more than about 200 lines of code. It's absurdly simple to implement. Just make sure your locking is all worked out. :) -Rick -Original Message- From: AustralianAccommodation.com Pty. Ltd.
